size, crispiness and Panang flavor were in range of ‘neither like nor dislike’ to ‘slightly like’ (5.0-6.5), while spiciness ranged from ‘slightly dislike’ ‘to moderately dislike’ (3.5). This information can be combined with the results of the ‘Just about right’ scale to determine the direction of improvement. The
